Getting blank page when trying to integrate with google spreadsheet.

I've attempted to authenticate my Google account using two different browsers, but the I get a blank page after clicking the Accept button.

Is this an issue with Google or Jotform?

Hello axual,

I'm sorry for the trouble caused to you.

I did check the google spreadsheet integration and I am unable to replicate the issue you are having. I tried to integrate one of my form and I was able to do the integration successfully.

I would suggest you to please try to clear your browser cache and see if that help you. The following guide should help you in clearing browser cache:  http://www.wikihow.com/Clear-Your-Browser's-Cache 

Do get back to us if the issue persists. You may also like to  let us know your browser details with which you are having this issue and we will take a look. You may also like to sign in to your gmail account in a separate tab before trying to do the google spreadsheet integration.

We will wait for your response.

Thank you!
